Sun-like magnetic cycles in the rapidly rotating young solar analog HD 30495
A growing body of evidence suggests that multiple dynamo mechanisms can drive magnetic variability on different timescales, not only in the Sun but also in other stars. Many...- publication PDF

Mercury's exospheric He I 58.4 nm emission: Dependence on the orbital phase
Aims. Emission from helium atoms in Mercury's exosphere at 58.4 nm was observed by the Mariner 10 spacecraft in the 1970s. This emission is due to resonant scattering of solar...- publication PDF
